A v2 app's inbound catch-hooks (inbound-webhooks). A catch-hook lets an external system such as Stripe, Zapier, Make, Home Assistant or an email router POST JSON to a secret URL that writes into a declared collection, so the app receives data with no agent online. Hooks are declared in the manifest (x-homespun-manifest.ingest) and materialized at deploy, so this tool has no create or delete: it reads back the URL, rotates a leaked one, and manages the opt-in signing secret. After deploying a manifest that declares a hook, list is what yields the exact URL to paste into the external system. Actions: list returns the app's hooks, each with its full secret URL, current rule collection, mode, wake and handshake settings, per-status delivery counts and signing-secret state; rotate mints a fresh URL secret for one hook by name and returns the new url once, after which the old url stops working immediately with no redeploy needed; set_signing_secret provisions or rotates a hook's signing secret, which is a different secret from the URL and is what a provider HMACs the body with, minting one returned once when `secret` is omitted or storing a provider value verbatim when it is passed, and never echoing it back; clear_signing_secret removes it. Signature verification currently ships dark: nothing verifies a signature yet.
